lf/XX_YY.png: Color images for view position XX in row (top to bottom) and YY in column (left to right)

attributes.dat: Attributes for the light field
		Example for stillLife_lf_3x3:
			768 //xRes => Image width
			768 //yRes => Image height
			3 //hRes => Number of views in horizontal position
			3 //vRes => Number of views in vertical position
			6.144000e+002 //dH			=> Parameters to calculate disparity from depth in HCI dataset
			288 //shift							=> Parameters to calculate disparity from depth in HCI dataset
			9.375000 //focalLength	=> Parameters to calculate disparity from depth in HCI dataset
															=> If focalLength=0, the values of depth.bin represent disparity directly
			-10.827057 //min_disp => Minimum disparity
			16.158417 //max_disp  => Maximum disparity

cross_pattern.dat: View sampling positions for crosshair configuration

depth.bin: Ground-truth depth (or disparity) map in single-precision floating-point (32-bit) and in raster scan 

disp_rel.png: Ground-truth disparity map converted from depth.bin (only for viewing purpose)
